Abstract (en)
[origin: EP1662423A2] A reader arrangement 22 for an electronic identficabion system is disclosed and claimed. The arrangement 22 includes a plurality of reader heads 22.1 to 22.4 for energizing transponders 28. 1 to 28.n to be read, and a controller 29 therefor. The controller 29 switches activation of the reader heads in a multi-phase sequential pattern including a first phase for activating a first set 22.1 and 22.3 of the reader heads and at least one further phase for activating a further set 22.2 and 22.4 of the reader heads. The switching is such that a complete cycle plus at least the first phase of a subsequent cycle is completed within a time period not longer than a reset period of the transponders. The reset period is the period between removal of an energizing signal from a transponder and the transponder re-entering a normal operational mode.
